[Machine] That the Messenger of Allah ﷺ said, "If one of you is invited and comes along with the Messenger, then that is permission for him." Said the scholar (may Allah have mercy on him), "This is with me, and Allah knows best about it. If there is no prohibition in the house, then there is no need for permission after the verse of the hijab was revealed."
أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا دُعِيَ أَحَدُكُمْ فَجَاءَ مَعَ الرَّسُولٍ فَذَلِكَ لَهُ إِذْنٌ قَالَ الشَّيْخُ رَحِمَهُ اللهُ وَهَذَا عِنْدِي وَاللهُ أَعْلَمُ فِيهِ إِذَا لَمْ يَكُنْ فِي الدَّارِ حُرْمَةٌ فَإِنْ كَانَ فِيهَا حُرْمَةٌ فَلَا بُدَّ مِنَ الِاسْتِئْذَانِ بَعْدَ نُزُولِ آيَةِ الْحِجَابِ
